Abstract

The theoretical and experimental study of free-field non-adiabatic alignment dynamics of asymmetric top molecules was presented. Investigations show the application of nonperturbative quantum mechanical theory and time-resolved imaging experiments with the help of iodobenzene and iodopentafluorebenzene. It was found that photofragment angular distributions measured the absolute degree of alignment at the revivals and shortly after the alignment pulse. The results show the new opportunities introduced by use of elliptically polarized short pulses to produce three-dimensional dynamical alignment.
